The Simien Mountains (also spelled Semien) lie in northern Ethiopia, north east of Gondar. They are a World Heritage Site and include the Simien Mountains National Park. The mountains consist of plateaux separated by valleys and rising to pinnacles. The tallest peak is Ras Dashen (4,543 m); other notable heights include Mounts Biuat (4,437 m) and Abba Yared (4,460 m).

Because of their geological origins the mountains are almost unique, with only South Africa's Drakensberg having been formed in the same manner and thus appearing similar. Notable animals in the mountains include the Walia Ibex, Gelada Baboon, Caracal and a few Ethiopian wolves.
